As Michael suggested, that `...' is a new feature of the Nix language,
not supported by the version of Nix currently installed on your system.
Thus, you should first install a newer version of Nix, which you should
be able to do like this:

  $ sudo nix-env -Ai nixUnstable

(`sudo' is needed here so that the new Nix is installed in the `default'
profile, not in your user profile.)

After that, you should be able to install Xorg.

Hope this helps,
Ludovic.
